Hamburger Menu In SXA

The following post was typed with one hand while my new born baby sleeps. 

The checklist:

• Create styles in SXA that will be attached to components.
• Add Row Splitter to header Partial Design. Add style Navbar.
• Add Plain HTML component to row 1. Add button snippet and adjust target class.
• Add Navigation component to row 1. Add style Navbar Collapse.
• Add bootstrap.js to theme.
